type Agent struct {

	// state stores a local representation of the node,
	// services and checks. Used for anti-entropy.
	State *local.State
	// contains filtered or unexported fields
}

Agent is the long running process that is run on every machine. It exposes an RPC interface that is used by the CLI to control the agent. The agent runs the query interfaces like HTTP, DNS, and RPC. However, it can run in either a client, or server mode. In server mode, it runs a full Consul server. In client-only mode, it only forwards requests to other Consul servers.

func New

  • initialize telemetry
  • create a TLS Configurator
  • build a shared connection pool
  • create the ServiceManager
  • setup the NodeID if one isn't provided in the configuration
  • create the AutoConfig object for future use in fully resolving the configuration

	req *structs.ConnectAuthorizeRequest) (allowed bool, reason string, m *cache.ResultMeta, err error)

TODO(rb/intentions): this should move back into the agent endpoint since there is no ext_authz implementation anymore.

ConnectAuthorize implements the core authorization logic for Connect. It's in a separate agent method here because we need to re-use this both in our own HTTP API authz endpoint and in the gRPX xDS/ext_authz API for envoy.

NOTE: This treats any L7 intentions as DENY.

The ACL token and the auth request are provided and the auth decision (true means authorized) and reason string are returned.

If the request input is invalid the error returned will be a BadRequestError, if the token doesn't grant necessary access then an acl.ErrPermissionDenied error is returned, otherwise error indicates an unexpected server failure. If access is denied, no error is returned but the first return value is false.

LocalBlockingQuery performs a blocking query in a generic way against local agent state that has no RPC or raft to back it. It uses `hash` parameter instead of an `index`. `alwaysBlock` determines whether we block if the provided hash is empty.

}

type ServiceManager added in v1.5.0 

type ServiceManager struct {
	// contains filtered or unexported fields
}

ServiceManager watches changes to central service config for all services registered with it. When a central config changes, the local service will be updated with the correct values from the central config.

func NewServiceManager added in v1.5.0 

func NewServiceManager(agent *Agent) *ServiceManager

func (*ServiceManager) AddService added in v1.5.0 

func (s *ServiceManager) AddService(req addServiceLockedRequest) error

AddService will (re)create a serviceConfigWatch on the given service. For each call of this function the first registration will happen inline and will read the merged global defaults for the service through the agent cache (regardless of whether or not the service was already registered). This lets validation or authorization related errors bubble back up to the caller's RPC inline with their request. Upon success a goroutine will keep this updated in the background.

If waitForCentralConfig=true is used, the initial registration blocks on fetching the merged global config through the cache. If false, no such RPC occurs and only the previousDefaults are used.

persistServiceConfig controls if the INITIAL registration will result in persisting the service config to disk again. All background updates will always persist.

service, chkTypes, persist, token, replaceExistingChecks, and source are basically pass-through arguments to Agent.addServiceInternal that follow the semantics there. The one key difference is that the service provided will be merged with the global defaults before registration.

NOTE: the caller must hold the Agent.stateLock!

func (*ServiceManager) RemoveService added in v1.5.0 

func (s *ServiceManager) RemoveService(serviceID structs.ServiceID)

NOTE: the caller must hold the Agent.stateLock!

func (*ServiceManager) Stop added in v1.6.2 

func (s *ServiceManager) Stop()

Stop forces all background goroutines to terminate and blocks until they complete.

NOTE: the caller must NOT hold the Agent.stateLock!

type TestAgent struct {
	// Name is an optional name of the agent.
	Name string

	HCL string

	// Config is the agent configuration. If Config is nil then
	// TestConfig() is used. If Config.DataDir is set then it is
	// the callers responsibility to clean up the data directory.
	// Otherwise, a temporary data directory is created and removed
	// when Shutdown() is called.
	Config *config.RuntimeConfig

	// LogOutput is the sink for the logs. If nil, logs are written to os.Stderr.
	// The io.Writer must allow concurrent reads and writes. Note that
	// bytes.Buffer is not safe for concurrent reads and writes.

	// DataDir may be set to a directory which exists. If is it not set,

const (
	TranslateAddressAcceptDomain TranslateAddressAccept = 1 << iota
	TranslateAddressAcceptIPv4
	TranslateAddressAcceptIPv6
